A TZMB3V9-GS18 is a single zener diode. It is a specific type of semiconductor device known as a zener diode. Zener diodes are used to regulate voltage by allowing current to flow in only one direction, while the reverse current will follow a specific, known voltage drop. Due to their linear and predictable behavior, they are commonly used in voltage regulation, voltage surge suppression and other applications requiring a quick response to changes in voltage over a wide temperature range.

A TZMB3V9-GS18 is a single zener diode device with a reverse breakdown voltage of 3V and a maximum power dissipation of 500mW. It has a lead spacing of 2.54mm and a working temperature between -55°C and +85°C. The device has a standard lead configuration with a 2mm pitch (pitch = distance between leads). Due to its small size and low power requirements, it is often used in electronic applications where space is limited, or where low power dissipation is required.

Application Field

The TZMB3V9-GS18 is often used in a variety of electronic applications. It is commonly used as a voltage regulator, surge protector and overvoltage protection. It is especially useful in situations where quick response times to changes in voltage levels are required. These include DC to DC converters, computer and communications systems, electronic voltage control circuits, power supplies, battery chargers and automotive systems.

It is also used in industrial and medical applications. It can be used to regulate and/or limit voltage levels in temperature measuring or sensing equipment, or to protect sensors and controllers from overvoltage damage. It is also useful in controlling and monitoring interference between power lines. The TZMB3V9-GS18 is an ideal solution when a low cost, low power and space-saving device is needed.

Working Principle

The TZMB3V9-GS18 is a single zener diode. A zener diode is a type of semiconductor device with a reverse-biased p-n junction . When voltage is applied to the diode in reverse bias, electrons and holes will be forced to recombine, releasing energy across the junction in the form of heat. As the reverse bias increases, the current through the junction will exceed the breakdown value, and the diode will begin to conduct electricity in the reverse direction. The voltage at which the diode begins to conduct is known as the zener voltage.

The TZMB3V9-GS18 is designed to operate at a reverse bias voltage of 3V. Once the reverse bias voltage reaches 3V, the diode will begin to conduct and the current will maintain at a constant level. This current will be limited to 500mW, ensuring that the diode does not become overloaded. Any voltage higher than the zener voltage will be clamped to the zener voltage, creating a stable, regulated output.

The TZMB3V9-GS18 is a powerful and efficient device, capable of quickly responding to voltage changes and ensuring reliable regulation across a wide temperature range. It is small, low cost and power efficient, making it an ideal solution for various industrial, medical and consumer applications.
